    A research group, funded by the Leibniz Association, investigates biases in collaborative information processing (e.g., online encyclopedias such as Wikipedia, Conservapedia, etc.) and focuses on three aspects that are expected to exert an influence: (1) norms of the online encyclopedia, (2) audience tuning, and (3) self-selection of users to online-environments.

    This project is a cooperation with Prof. Dr. Steffen Nestler (University of Münster), that is funded by the German Research Foundation (OE 604/3-1, NE 1485/8-1) and follows up on an earlier project (OE 604/1-1, NE 1485/5-1) and examines hindsight bias in Wikipedia. Specifically, we test several explanations for the finding that only Wikipedia articles about disasters (but not articles about elections, official decisions, personal decisions, scientific discoveries, sports events) contained a hindsight bias. Moreover, we investigate the underlying mechanisms of the reception effects – the finding that biased articles increase hindsight bias in readers of those articles.

    We investigate several biases in information processing (hindsight bias, confirmation bias) in the context of legal decision making (e.g., criminal law, patent law) with professional decision makers or experts (e.g., judges, patent law attorneys).

    Much research has shown that memory is fallible and malleable. On the one hand, our focus lies on the reversibility of social influence on memories. On the other hand, we search for indicators that might help in detecting previous social influence on memory.

    A variety of research investigates how individuals utilize information about other individuals’ judgments and decisions (i.e., advice) to adapt their own judgments and decisions. Next to increasing accuracy by exploiting the wisdom of crowds, advice taking also yields interpersonal benefits, such as shared responsibility and increased likelihood of future cooperation. This project investigates a necessary precursor to advice taking that has been largely neglected by existing research, namely how individuals seek advice. We developed a sampling paradigm of advice taking that allows individuals to seek any number of advisory estimates before revising their judgment or decision. This expanded paradigm allows to investigate advice taking in a more ecologically valid setting, yields new insights for developing a comprehensive theory of advice taking, and sheds new light on current evaluations of the adaptivity of individuals’ utilization of advice.

    How do (negative) media reports about a criminal case affect verdicts? Many studies have investigated this question. We are currently conducting a meta-analysis in order to provide a quantitative summary of previous research.

    Moral rules and judgements about which actions do violate these rules and which do not (= moral judgements) are essential for organizing human cohabitation in groups and societies. Frequently, especially powerful people (such as politicians, teachers, and judges) make the socially most relevant moral judgments. For instance, powerful people can lay down which moral rules apply to a group by their behavior as a role model. The current project focuses on the question of how power influences moral judgement, i.e. whether powerful people come to other moral judgements than low-power people. Specifically, the project is dedicated to the question of whether the roles of the actor (=person who potentially violates a moral rule) and the beneficiary (=person who would benefit from a potential moral violation) moderate the effects of power on moral judgement.
